Lone Pine Fans and Earthquakes

At Lone Pine, California, a distinct alluvial fan near town is offset by
the Lone Pine Fault. Closer to the range front, extensive
bajada-forming fan surfaces are littered with granitic boulders. We
sampled boulders from fan units with different relative weathering
intensities and used the resulting cosmogenic data to both estimate fan
ages and earthquake recurrence intervals.
